3 Claims.

This invention relates generally to systems for the communication of intelligence and more particularly to the communication of advertising material in moving carriers.

The main object of the invention is the dissemination in an eflicient and economical manner of advertising in moving carriers and to the correlation of the subject matter of said advertising with the relative position of the carrier.

Another object of the invention is the provision of a system of advertising whereby the safety of the passengers in the moving carrier is increased because the operator of the vehicle is able to concentrate upon the maneuvering thereof without being disconcerted in conveying information to passengers.

Another object of the invention is the-taking advantage of the lack of mental preoccupation on the part of the passenger and the conveying to 20 him of advertising material at a time when his mind is in a high state of psychological receptivity.

Another object of the invention is the elimination of the human factor so that information is conveyed to the passengers in a constant manner, unblemished by fatigue or vocal difficulties of the operator or announcer.

Another advantage of the system is its universal adaptability so that the subject matter of the advertising conveyed to the passengers of the carrier may be changed within a very short space of time whenever change becomes advisable and may be examined by the person controlling this system and edited before it is sent out to the passengers in the carrier.

These objects and other incidental ends and advantages of the invention will more fully appear in the following description and in the appended claims.

The word advertising as used in this specification and the appended claims is to be given a broad interpretation, meaning not only to call attention to things to purchase, but also to inform, to give notice, advice or intelligence.

I attain these objects by two preferred embodiments of the system of advertising, the subject of this invention, as illustrated in the accompanying drawings, in which Figure l is a schematic diagram of the advertising system as applied to the dissemination of auditory intelligence, while Figure 2 is a similar diagram of this system as applied to the dissemination of visual material.

Numeral l designates an electric motor having affixed to one end of its driving shaft a spur gear I l which is in mesh with another spur gear I2, the

latter gear being affixed to one end of a shaft l3 upon which is mounted a drum member I4. Numeral l5 indicates a drum member mounted upon a shaft l6 having aflixed thereto at one end a pinion I! which is in mesh with a spur gear l8, the said gear being mounted upon a short shaft l9 which has affixed to an end thereof a radial arm 20. Said arm 20 has affixed to the outer end thereof a short projecting cone member 2| adapted to actuate a push button two point make 10 switch 22. Continually encircling drum l4 in one direction and drum l5 in another direction is a hard steel wire 23. Said wire is adapted by passage through the axes of solenoids 24 and 25 to have its molecular structure so rearranged by the changes in magnetic flux caused by energization of the said solenoids 24 and 25 that, when the wire 23 passes through the axis of a solenoid 26, the moving lines of force which surround the said wire 23 induce a fluctuating current in the windings of the solenoid 26. Numeral 21 designates a magnetic solenoid while 28 indicates an armature adapted to be drawn within the said solenoid 2'! when it is energized. Armature 28 has its outer end expanded to form a braking shoe which in 25 operative position is in frictional engagement with a brake drum member H, the latter being a flange portion of the drum l4. The braking shoe portion of armature 28 is held in contact with brake drum M by means of the expansive spring 30 29.

Numberal 30 indicates a microphone while numeral 3| is an audio frequency amplifier connected therewith. A loud speaker 32 is connected to the output of an audio frequency amplifier 33. Numeral 34 is an elevator car having suitably positioned on its ceiling a loud speaker 35 which is connected to the output of an audio frequency amplifier 36. Numeral 31 represents an electrical oscillator operating at any suitable super-sonic frequency.

All of the relays shown in the drawings are ordinary instantaneous acting relays and the armatures therefor are shown in their nonactuated position. Numeral indicates a relay having an 4 armature 4| and a contact therefor 42. Numeral designates a relay having an armature 46 and a contact therefor 41. Numeral 50 indicates a relay having armatures 5| and 52 and contacts therefor 53 and 54. Numeral 55 indicates a relay 0 having armatures 56 and 51 and contacts therefor 58, 59 and 59'. Numeral 60 indicates a relay having armatures BI, 62, 63 and 64 and contacts therefor 65, 66, 61 and 68. Numeral 10 indicates a relay having armatures ll, l2, l3 and 14 and 55 contacts therefor 15, 16, 11 and 18. Numeral 80 indicates a relay having armatures 8|, 82 and 83 and contacts therefor 84, 85, and 86. Numerals 81 and 88 are push button two point make switches. Numerals 89 and 89 are incandescent lamps colored red and green respectively. Numeral 90 is a relay having an armature 9| and a contact therefor 92, while numeral I is a relay having armatures |0|, I02 and I03 and contacts therefor I04, I05 and I06. Numeral H0 is a. relay having armatures H2, and H3 and contacts therefor H4, H5 and H6. Numeral I20 is a relay having armatures |2|, I22 and I23 and contacts therefor I24, I25 and I26. Numeral I30 is a toggle switch adapted to be thrown in either of two positions as indicated by the arrows adjacent thereto on the drawings or in a neutral position as it is shown in the drawings.

Numerals |3| and I3I' indicate insulating tie bars mechanically connecting the switch blades I32, I33, I34, I35, I36, |31, I38, I39, I40 and IN, while letters A, B, C, D, E, F, G, H, I and J represent fixed contact points on the said toggle switch I30.

Numerals |5I, I52, I53, I54, I55, I56, I51, I58 and I59 indicate switch contact buttons which are adapted to contact with contact points I60, I6|, I62, I63, I64, I65, I66, I61 and I68 respectively, as the said contact buttons are depressed by a projection I45 extending from the portion of the elevator car 34 opposite the row of contact buttons I 5| to I59 inclusive. units formed by the pairs of contact buttonsand their adjacent contact points are disposed along the elevator shaft so that the various circuits appertaining thereto will be closed in proper relation to the vertical position of car 34 within the shaft, as will be more particularly described below.

Now will be described the operation of the embodiment of the subject of this invention as shown in Figure 1.

Assuming that, due to previous operation, the wire 23 now carries a recording thereon in the form of a displacement of its molecules, and also assuming that car 34 is at such a level in the shaft that its projection I45 is situated between contact buttons I52 and I53, switch I30 is raised to the position marked play. This brings switch blade I33 in contact with switch point B and allows current to flow from the power supply indicated by the word line into solenoid of relay 55. Relay 55 now energized displaces armatures 56 and 51 so that they now contact contact points 58 and 59. Armature 56 thus closes the circuit connected with the solenoid of relay 50 so that it is in readiness'for energization when current is permitted to flow from the line through relay 0 by means of a conductor I 10. It is to be noted at this point that the button contacts I5| I53, I54, I56, I51 and I59 are all connected to the power supply through a chain connection formed by armature I03, contact I06, armature II3, contact 6, armature I23 and contact I 26 by means of a conductor I12, so that when car 34 starts to move upwardly within the shaft, projection I45 strikes against contact button I53 and depresses it, thereby causing contact button I53 to touch contact point I62. Current then flows from contact point I62 to armature II2 through contact point 5 and thence through relay I I0 and a conductor I13. Current also flows from contact point 5 along the conductor I10 to contact point 58. Relay 55 having been previously energized by the movement of The switching.

toggle switch I30 as above set forth, current flows from contact point 58 through armature 56 to the solenoid of relay 50, the return circuit therefrom being completed by means of a conductor I14., With the energization of relay 0, armature H3 is displaced so that it no longer contacts contact point 6 and armature II2 no longer contacts contact point 5. This latter disruption would de-energize relay II!) but for the fact that armature II I isdisplaced so that it contacts contact point II4. Relay 0 thus continues in an energized state by means of the circuit formed by conductor I13, contact point II 4, armature III, armature 3|, contact point 92, a conductor I and conductor I12.

Relay 50 having been energized as above described, current is enabled to flow from the line through a conductor |15 to contact point 53 thence to armature 5|, thereby energizing relay 45, the return of this circuit is completed through conductor I14. The contact point 53 and armature 5| also allow current to flow along a conductor to the motor In and the braking mechanism solenoid 21 and thence through a return circuit formed by a conductor I11 and conductor I14. Current which has been flowing along conductor I16 also branches off to flow in a conductor I18 to the switch 22. It is to be noted at this point that switch 22 is so constructed that it remains normally in an open circuited position although shown closed on the drawings. With switch 22 open, the brake shoe 28 is released and motor I0 starts to revolve. This causes wire 23 to travel and induce an alternating current in solenoid 26, the circuit comprising a ground conductor I80, solenoid 26, a conductor I82, armature 51, contact 59, a conductor I83, contact 54, armature 52, a conductor I84, the input of amplifier 36, and its ground return |8|. Solenoid 26 acting as a pickup coil, the audible frequencies induced therein are converted to sound in the speaker 35.

Relay 45 having been energized as set forth above, an auxiliary circuit is completed through its solenoid, comprising conductors I15, I85, armature 4|, contact 42, conductor I86, armature 46, contact 41, solenoid of relay 45, and conductor 14. From this same auxiliary circuit, current will flow along conductors I16 and I18, thus assuring the motor I0 of a continuous supply of power even after current ceases to flow along conductor I10 thus de-energizing relay 50.

The motor I0' continues to revolve until all of wire 23 has passed through the pick up coil 26, at which time, a complete cycle having been completed, cone'member 2| will strike switch 22 thus completing the circuit via conductors 18, I19, to relay 40, with a return through conductor I14. Relay 40 now energized displaces armature 4| so that it no longer contacts contact 42, thus breaking the auxiliary circuit so that current no longer flows along conductors I86. Assuming that relay 50 is now de-energized as will be described below, motor I0 and braking solenoid 21 cease operating, thus allowing spring 29 to force shoe 28 in contact with brake drum member M. This brings all the related mechanism to a stop, but not before inertia has carried cone member -2| beyond switch 22 so that it returns to its button 'ihis would tend to energize relay I20 but for the fact that the circuit formed by conductor H2, contact I26, armature I23, contact iii. armature 3, contact I05, armature I03, button I54, contact I63, armature I22, contact I25, relay I20 and conductor I13 is broken between contact H6 and armature H3, since relay H is still energized. Car 34 continues upward and depresses button I53, which contacts contact I54, and completes the circuit energizing relay 90, so that armature 9| is displaced out of contact with contact 92. This displacement of armature 9| opens the circuit to relay H0, and stops current from flowing along conductor I10. With the cessation of current in conductor I10, relay 50 becomes de-energized, allowing armature 52 to recede from contact 54, thus cutting out the signal [input to amplifier 36, and also allowing armature to recede from contact 53 which would stop motor I0 but for the circuit maintained by relays 40 and 45 as set forth above.

As car 34 continues upward, projection I45 will next strike button I56 which upon contacting contact I65 will initiate a sequence of relay actions similar to that which occurred when button I53 was depressed, except that this time relay I00 will be energized and current will flow along the conductor |1I, to a group of relays associated with the next floor, said group not being shown on the drawings.

It is to be noted at this point that this embodiment of the invention is capable of being used with any number of elevator cars using speakers, serving any number of floors. One drum and wire assembly, including drums I4 and I5, wire 23 and related mechanism will be required for each car and floor. One group of relays similar to relays 40, 45, 58, 55 and 80 will be required for each car and floor. One group of relays similar to relays 90, M0, M0, and I20, and one group of contacts similar to contacts and buttons i5II80, I52|8I, i53-I62, I54-I63, |55-I85, I51-|66, I58|65, i59|68 will be required for each shaft, assuming that there are three floors on each shaft. Where there are more than three floors on a shaft, additional sets of three contact buttons are added as well as additional relays similar to relay 100. One amplifier like amplifier 36 is used for each car, while only one each of microphone 30, amplifier 3|, speaker 32, amplifier 33, oscillator 31, relays and 80, switches 81 and 83, lights 89 and 89 is used for entire installation regardless of the number of shafts, floors or cars. One switch like switch I30 is used for every car and every floor, all switch blades corresponding to switch blades I35, I36, I31, I38, I39, I40 and MI and contact points corresponding to contact point A, being connected in parallel.

The contact buttons |5| to I59 inclusive are spaced along the shaft in groups of three ad acent each floor landing, as indicated on the drawings, and the above described sequence of contact and relay operations exists universally between all fioors whether the car 34 is ascending or descending. The center button in the group of three releases the relays directly associated with the contact buttons, while the next outer button in the group of three, actuates the relay associated with the sound mechanism for the floor which the car 34 approaches. By properly positioning the contact buttons such as I53, going up, or I54 going down, the advertising material concerning the following floor may be made audible in the car 34 either while it is loading up and discharging at the prior floor or after it actually begins to move towardthe next floor.

Now will be described the mechanism for re- I cording the advertising material on the wire 23. Switch I30 is moved to the position marked "Record on the drawings, so that in addition to lowering tie bar |3|, it also lets tie bar |3| drop thus completing the contact between contact A and blade I32. Blade I34 contacts contact C which completes the circuit from conductor I to conductor I81, thus energizing relay 60, the

return being eflected through conductors I88 and the return of this circuit being completed through,

conductor I92, blade |4|, contact J, and conductors I93 and I13. The motor |0 will now revolve and will run a complete cycle, being again controlled by switch 22 and relays 40 and 45 as heretofore described. As soon as bulb 89 lights up, the operator may begin to talk into microphone 30, the voice currents of which, after passing through amplifier. 3 I, go via a conductor I94, contact 18, armature 14, conductor I95, contact A, blade I32, conductor I96, contact 68, armature 64, conductor I91, to the solenoid 25, which records them on wire 23 by magnetic induction. Energization of relay 10 also completes a circuit from oscillator 31, via conductor I98, contact 11, armature 13, conductor I99, blade 938, contact G, conductor 200, contact 61, armature 83, and conductor to the solenoid 24, which by recording a supersonic frequency on the wire 23, before it passes through solenoid 25, serves to clear the wire of any previous recordings. Energization of relay 10 by depressing switch 81 also closes an auxiliary circuit which keeps relay 10 energized with only a momentary depression of switch 81. This circuit is comprised by conductors E13 and I93, contact J, blade |4|, conductor I82, relay 10, contact 15, armature 1 I, conductor 202, blade I40, contact I, conductor 203, contact 42, armature 4|, conductor I85, and conductor H5. It will thus be seen that relay 10 will remain energized until motor 10 has run wire 23 a complete cycle, at which time, relay 10 becomes de-energized and the red light 89 goes out.

After recording the sound which has been recorded on wire 23 may be played back so that the operator may check on its accuracy or quality. In order to do this, switch I30 is kept in its record position, and switch 88 is depressed. This lights green light 89' and energizes relay 80, while relay 60 remains energized owing to the position of switch I30. Armature 8| acts identical with respect to relay 80 as does armature H with respect to relay 10, that is armature 8| serves to keep relay 80 energized, after pressure is released from switch 88, until motor I0 has completed a full cycle of the wire 23. Energization of relay 80 also serves to complete the circuit to the motor I0 and brake solenoid 21 via conductors I16 and I89, contact 85, armature 8|, conductor 203, contact H, blade I39, conductor 204, armature 82 and contact 85. Voice currents induced in solenoid 28 instead of being fed to amplifier 36 are fed to amplifier 33 via the circuit comprising conductor I83, armature 51, contact 59, conductor 205, contact E, blade I36, conductor 296, armature 83, contact 66, conductor 291; return being completed through ground circuits I89 and I8l. After wire 23 has completed one full cycle, sound in speaker 32 ceases, and light 89' goes out. If this audition of the recorded material is satisfactory to the operator, switch I30 is raised to the position marked Play when the recording on wire 23 will be made audible in the car 34 at the proper position, or if the recording is unsatisfactory, it may be re-recorded as was done originally, following the procedure outlined above.

In the embodiment shown in Figure 1, if buttons I52, I55, and I58 are situated at the basement, first floor, and second floor respectively,

- then motor I0, drums I4 and I5, together with associated apparatus, and relays 40, 45, 50, 55, and 60 constitute equipment for the first floor, while conductors I69 and "I would be connected to equipment for the basement, and second floor respectively. Conductors I69 and I 1|, would then feed into apparatus identical with that into which conductor I10 feeds.

In Figure 2, in which an embodiment of the invention is shown, wherein the advertising material is visually disseminatedjnumeral 2|!) represents a reversible electric motor having binding posts 2I I and 2 I 2 to the rotor winding thereof, and binding posts 2 I3 and 2 I4 to the stator wind: ing thereof. A motor shaft 2I5 has mounted thereon a sprocket 2I6 which is connected by means of a chaim 2" to another sprocket 2I8. Sprocket 2 I8 is mounted upon one end of a shaft 2I9, said shaft having mounted thereon, a drum 220. Shaft 2 I5 has mounted thereon a drum 22I which carries in conjunction with drum 220, a continuous belt 222, having advertising material thereon as indicated by the dotted portions 223. The outer end of shaft 2I5 has affixed thereto a radial arm 224 having at its end a conical member'225 adapted to depress the push button of a two point break switch 226, said switch being normally in a closed circuit position. Numeral 221 designates a magnetic solenoid the winding of which is provided with a center trap, armature 28, spring 2 9 and brake drum I4 are identical with the structure represented by the same numerals on Figure 1. Numerals 230 and 240 represent ordinary instantaneous acting relays shown in their nonactuated position. A single pole, double throw switch 250 is adapted to be thrown to contact 25I or 252 by meeting with projections 266, 26I, 262, 263, which are affixed to the wall of the elevator shaft 259. All of the apparatus shown in Figure 2 with the exception of the shaft wall 259 and the projections thereon is situated in the elevator car.

Assuming the car to be so positioned in the shaft that switch 250 is situated between projections 269 and 26I, the car moving upward will cause projection 26I to force switch 250 in contact with contact 252. Current will now flow along conductor 210,,switch blade 250, conductor 21I, through relay 230, conductor 212, switch 226 (normally closed though shown open in the drawings), and conductor 213. This energizes relay 230 so that current flows via contact 233, armature 23I, and conductor 214 to solenoid 221, the return of which is completed through center tap 215, switch 226 and conductor 213, which releases the brake 28 from drum I4. Energization of relay 230 also allows current to flow to the motor via conductors 214, 216, 211, post 2I4, post 2I3, conductor 218, armature 232, contact 234,

conductor 219, post 2I2, post 2| I, and conductor 260. Assuming thatprojection 26I is positioned at the first floor landing as indicated on the drawings, the motor 2| 9 with its associated drums will wind into place, where it may be viewed by passengers in the elevator car, advertising material pertaining to the second fioor. As soon as the advertising material on belt 222 is aligned opposite an orifice in the casing therefor not shown in the drawings, cone members 225 will strike switch 226, thus breaking the circuit, deenerglzing relay 230, cutting off current to the motor 2IIl and the solenoid 221.- Motor 2I0 will stop and the brake will be applied, but only after cone member 225 has passed switch 226 leaving itsin readiness for the next impulse from switch 2 ll.

When the elevator moves down in the shaft the same procedure is repeated except that since switch blade 250 strikes contact 25I, relay 240 is energized, this energizes solenoid 221 through the circuit comprised by conductor 210, blade 259, contact 25! contact 243, armature 24I conductor 218, and conductor 28I The reversible motor 2 I 0 is now caused to rotate in a direction opposite to that which it took when relay 239 was energized, the circuit being comprised by conductor 210, blade 256, contact 25 I, contact 243, armature 24I, conductor 218, post 2I3, post 2I4, conductor 211,.armature 242, contact 244, conductors 282 and 219, post 2I2, post 2, conductor 2B0, switch 226 and conductor 213.

The apportionment of the time allotted to the going up or going down advertising material is made by adjusting the vertical position of projections 260 to 263 inclusive with relation to the adjacent floors.

At the moment before reversal of motor 2I0, the conical member 225 is just adjacent the switch 226. To avoid a cessation of current to the motor 2I0 as it opens switch 226 upon the starting of the mechanism in the reverse direction, an auxiliary circuit by-passing the said switch 226 is provided. This by-passing circuit comprises a conductor 290, a brush 29!, a slip ring 292, a contact 293, a springably mounted switch blade 294, a slip ring 295, a brush 296 and a conductor 291. Slip rings 292 and 295 are mounted upon but insulated from shaft 2I5. Blade 294 is normally closed but centrifugal force causes a weight 294' mounted thereon to draw the blade 294 to its open position, this occurs, however, only after cone member 225 has passed switch 226.

While speaker on Figure l and belt 222 in Figure 2 are shown or stated to be positioned in the moving elevator car, it would not be a departure from the scope of this invention to mount such speaker or belt at or adjacent the landings of the elevator cars to convey advertising material to awaiting passengers-to-be, said advertising material being in any way correlated to the relative positioning of the cars Within the shafts.

As described, belt 222 carries the advertising material, but it may readily be seen that slides or film, both moving and stationary are, capable of being projected on .a surface equivalent to belt 222 and thereby effectuate the purposes heretofore mentioned. The displacement of the slides or moving of the film could be accomplished by mechanism similar to the actuation of belt 222.

This invention is not to be limited to the particular details of construction described above as many equivalents will suggest themselves to those skilled in the art. It is accordingly desired that the appended claims be given a broad interpretation commensurate with the scope of the invention within the art.
